Which term is a combination of symbols that represent the elements in a compound?

• A. Molecular Formula
• B. Elemental Notation
• C. Symbolic Representation
• D. Chemical Formula

Answer: (D)

Think about how we show what a compound is made of using symbols from the periodic table. A chemical formula is the shorthand that uses element symbols and subscripts to show how many atoms of each element are in a compound, giving the exact composition in a compact form. For example, H2O tells you there are two hydrogen atoms and one oxygen atom in a molecule of water. This concept applies to many substances, including ionic compounds like NaCl, where the formula indicates the ratio of sodium to chlorine. While a molecular formula serves a similar purpose for substances that exist as discrete molecules (indicating the number of each atom in a molecule), the broader and correctly fitting term for a combination of symbols representing the elements in a compound is chemical formula.
